Grizzly vs Black Bear: Understanding Their Differences

The Grizzly and Black Bear are North American bear species with distinct characteristics. This lesson explores their differences, from physical traits to behaviors.

Grizzlies are larger, with a weight of up to 700 lbs, and have a prominent shoulder hump. Black bears are smaller, maxing out around 400 lbs, with no shoulder hump.

Grizzly bears have longer, typically brown fur with white tips, giving a grizzled appearance. Their claws are long for digging. Black bears have shorter, darker fur and shorter claws for climbing trees.

Grizzly bears favor open spaces like tundra and coastal areas. Black bears prefer forested regions. Their habitats can overlap, but their preferences reduce competition.

Grizzlies have a more varied diet, eating meat and plants. They often prey on larger mammals. Black bears are mostly herbivorous but will eat fish and insects.

Grizzlies are solitary and territorial. They can be more aggressive, especially females with cubs. Black bears are less territorial and more likely to flee than fight.

Grizzly bears are considered more at risk than black bears. They require larger territories, which are increasingly threatened by human activity, while black bears adapt more readily to different environments.
